Most of the other rads went cold, but at least one stayed hot i can only think the seats on the valves were not sealing correctly, but the other rad was still cold
Any advise would be welcome.
We've got a 10mm microbore central heating system.
Completed drained system, tapped into plumbing to fit new rad. Refilled system, with new Fernox.
All other radiators are hot, and fine. However one small radiator in en-suite will not get hot despite bleeding...
